warranty preservation
It is actually quite noticeable. I posted before and after dyno charts in the dyno thread. I got 42 at the wheel horsepower and 21 at the wheel torque increases, if memory serves. As well as much flatter torque curve that peaked at a lower RPM. Shifting remained smooth and firm so I did not notice a huge difference in that.
I have both and dyno tested both. Horsepower gains are similar with the Livernois tune coming in slightly higher on the dyno. Torque gains were better with the Livernois tune as well. I did not care for the transmission shifting hard though. The Livernois towing tune was better in that regard but the FP tune outperforms that one.
Interesting. I remember your thread when you first got the FP tune and it seemed drivability was greatly improved but was lacking on the torque. So I was surprised when I saw your livernois dyno and the hp gain was similar but torque was better. I’m not looking to have the fastest truck or having the tires screeching from every traffic light so I think the drivability piece may be my deciding factor. Just hate the fact the FP tune is substantially more than the Livernois.
There’s a sale right now. I’m highly considering but still on the fence between livernois and Ford https://www.levittownfordparts.com/...MI3dmWwrjl7AIVYiCtBh1Ekg7KEAQYAiABEgLaKfD_BwE
That's where I bought mine from. It's perfectly good.
Levittown has great pricing so I’d definitely purchase from them. It’s still $123 more than Livernois which is what makes me so on the fence about which to get. I guess I’ll keep it on the back burner for now.
My apologies Scott. I did not realize what thread I was in when I answered the question. You are absolutely correct and I'll pay closer attention in the future.
It wasn't really directed at you as much as a general statement to all.
